I'm new to this phone system stuff. Just upgrading my MICS from 4.1 to 6.1, but my phone just blinks. When I put my original 4.1 back on it works fine. Any ideas why changing it to 6.1 doesn't work and ideas on how to make it work. I called a local phone system reseller and he said to drain the cap in the nvram cartridge, I tried that too, but it didn't work. Should I drain the cap in the MICS cabinet also?
